Current through Register Vol. 48, No. 9, September 27, 2024
(a) A solid waste exhibits the characteristic of ignitability if a representative sample of the waste has any of the following properties:
(1) It is a liquid, other than a solution
containing less than twenty-four percent (24%) alcohol by volume and at least
fifty percent (50%) water by weight, that has flash point less than 60 °C
(140 °F), as determined by using one of the following ASTM standards: ASTM
D93-79, D93-80, D3278-78, D8174-18, or D8175-18 as specified in SW-846 Test
Methods 1010B or 1020C (all incorporated by reference, see section
260.11).
(2) It is not a liquid and
is capable under standard temperature and pressure, of causing fire through
friction, absorption of moisture or spontaneous chemical changes, and when
ignited, burns so vigorously and persistently that it creates a
hazard.
(3) It is an ignitable
compressed gas.
(i) The term "compressed gas"
shall designate any material or mixture having in the container an absolute
pressure exceeding 40 p.s.i. at 70 degrees F or, regardless of the pressure at
70 degrees F, having an absolute pressure exceeding 104 p.s.i. at 130 degrees
F; or any liquid flammable material having a vapor pressure exceeding 40 p.s.i.
absolute at 100 degrees F as determined by ASTM Test D-323.
(ii) A compressed gas shall be characterized
as ignitable if any one of the following occurs:
(A) Either a mixture of thirteen percent
(13%) or less (by volume) with air forms a flammable mixture or the flammable
range with air is wider than twelve percent (12%) regardless of the lower
limit. These limits shall be determined at atmospheric temperature and
pressure. The method of sampling and test procedure shall be the ASTM E681-85
(incorporated by reference, see section 260.11), or other equivalent methods
approved by the Associate Administrator, Pipeline and Hazardous Materials
Safety Administration, U.S. Department of Transportation.
(B) It is determined to be flammable or
extremely flammable using
49 CFR
173.115(l).
(C) Using the Bureau of Explosives' Open Drum
Apparatus (see Note 1), there is any significant propagation of flame away from
the ignition source.
(D) Using the
Bureau of Explosives' Closed Drum Apparatus (see Note 1), there is any
explosion of the vapor-air mixture in the drum.
(4) It is an oxidizer. An oxidizer for the
purpose of this subchapter is a substance such as a chlorate, permanganate,
inorganic peroxide, or a nitrate, that yields oxygen readily to stimulate the
combustion of organic matter.
(i) An organic
compound containing the bivalent -O-O- structure and which may be considered a
derivative of hydrogen peroxide where one or more of the hydrogen atoms have
been replaced by organic radicals must be classed as an organic peroxide
unless:
(A) The material meets the definition
of a Division 1.1, 1.2, or 1.3 explosive, as defined in 261.23(a)(8), in which
case it must be classed as an explosive,
(B) The material is forbidden to be offered
for transportation according to
49 CFR
172.101 and
49 CFR
173.21,
(C) It is determined that the predominant
hazard of the material containing an organic peroxide is other than that of an
organic peroxide, or
(D) According
to data on file with the Pipeline and Hazardous Materials Safety Administration
in the U.S. Department of Transportation, it has been determined that the
material does not present a hazard in
transportation.
(b) A solid waste that exhibits the characteristic of ignitability has the EPA Hazardous Waste Number of D001.
